Neutral, I wouldn't have been able to predict the way the NS's vario-whatzit would behave in practice, I think adding an extra level of complexity can only be evaluated on the test slope. Speaking of which, if any snowboarding companies would like a volunteer to test their stuff, I've got some free time....

Seriously though, I hope their testing is showing some actual benefit. I'd hate for it to be like adding yet another blade to their razor just so they can sell "new and improved".
